To (1,27, whom it may concern:

Be it known that l, GEORGE L. ZUoKEn, a citizen of the United States ofAmerica, and a resident of East Orange, in the county of Essex, in theState of New Jersey, have invented certain new and. useful improvementsin Apparatus for Treating Bailing-Tools, of which the following is aspecification.

This invention relates to an im 'irownnent in an apparatus for sprayingor treating the sur face of builing-wheels, which consists in the use ofa rece tacle for containing a quantity of oil, grease, or suitablepolishing or abrasive materials in solution, which receptacle T 5suitably supported and has an outlet or nozzle in proximity to abufiing-wheel and has cooperating with it means for supplying air underpressure, so that the material within the receptacle may be sprayed ontothe buflingwheel as desired.

As bufiing materials are now applied. they become caked, hardened, orpolished on the bui'iing-wheel, and thus greatly lose their efficiency.It is therefore necessary in actual 5 practice to keep the surface ofthe buffingwheel in a soft and fluffy condition by the use of a suitabletool; but in doing this the greater part of the wheel is from time totime worn away. .It is therefore recognized that the 3 working life ofthe boiling-wheel is very lim ited; but by spraying it with a suitableliquid .l am enabled to retain the buliing-surface in a soft and fluffycondition. 1 his reduces the necessity of dressing this surface of thebuffing-wheel to a mininuun.

My invention is not, lmwever. limited to spraying oil or grease onto alnifling-wheel to soften the buiiing compound previously applied; butthe receptacle may contain the bu lf- 4 ing compound in solution, sothat itmay itseli be sprayed on the tool in suiiiciently liquid state toproduce the desired effect.

My invention therefore consists in the apparatus for treatingbailing-wheels, as will be hereinafter described, and then definitelyset forth by the claims thereof.

in the drawings accompanying and forming part hereof, and which show myinvention in the embodiment.lnow prefer, Figure l is a perspective viewof one form of my invention. 5o Fig. 2 is a sectional view of the same.Fig.

3 is a perspective view of a slightly-modiiied way of feeding thematerial; and Fig. eiis a side view, partly in section.

Referring now to the details of the draw ings by numerals, andparticularly to Figs. i and 2, 1 indicates a suitable receptacle whichmay be of any desired construction, but is illustrated as couiprising areceptacle proper,

1, and a screw-threaded cap 2, the latter being provided with two pipesor tubes 3 and a and a valve or cock 5. The pipe or tube 3 is merelyscrewed to the cap or cover 2' and has an opening 6 of very restrictedsize leading into the receptacle for a purpose to be here inafterdescribed. The upper end of the tube or pipe3 colun'iunicatcs with ahorizontal pipe 7, one end of which leads to a coinpressed-air tank 8,and the other end isfornied into a noz zle 9, as clearly shown. Betweenthe tank 7 and the T 10, leading to the tube or pipe 3, is

a valve or cock 11, which controls the supply of compressed air, and thearrangement of the parts so far described such that when the valve 11 isopened the air passes both to the horizontal pipe 7 of the nozzle .l andalso through the vertical tube or pipe :1 into the receptacle 1 andcreates :nill'ioient n'essureiu said receptacle to forcenny materialcontained therein out of the tube or pipe This pipe 30 i also leads to apoint in proximity to the l. ulling-wheel and terminates in a nozzle in,adjzuzent to and coactinp; with the conipressml air nozzle 5). itfollows from the construetion so far described that if an oii or gream 5or a bu'iiing compound in solution iscontaincd within the receptacle andthe valve 11 is opened the compressed air passes down into thereceptacle andcreates such pressure there in as to cause the materialwithin said recep- 9 tacle to pass out of the pipe or tube r to thenozzle 12. dimultaneously the air also passes through the pipe 7 to thenozzle 3), and this nozzle is so formed and directed as to force withgreat pressure any material passing out of the nozzle 12, with theresult that the material forced to the nozzle 12 is sprayed onto thebuffing-tool. If the material contained within the receptacle is merelygrease or an oil for the purpose of softening the bufiingtool, thequantitysupplied to the' tool may be easily controlled by the operator,whose hand may be kept on the valve 11. Likewise, if the receptaclecontains buffing material the amount of this material supplied to thebuffing-tool may be controlled in the same way. I have shown a valve orpetcock 5, which is for the purpose of enabling the operator to relievethe pressure of air in the receptacle when it is desired that nomaterial be fed to the nozzle 12. This will be found useful, asotherwise even after the operator shuts off the supply of compressed airthe air-pressure in the receptacle might be suflicient to feedconsiderable material to the nozzle, which owing to the fact that noair-pressure is supplied to the nozzle 9, would simply trickle off ofthe nozzle 12 and go to waste. In its preferred form the handle of thisvalve or cook 5 is connected to the valve 11, so that as the valve 11 isopened the valve 5 is closed, and vice versa. This absolutely preventsany waste of material.

In the construction shown inFigs. 3 and 4 I instead of having thematerial fed by air-pressure it is fed by gravity, and in this form thematerial is contained within a receptacle 20, which is sufficientlyraised above its nozzle 21 to feed the material thereto by gravity whenthe valve 22 is opened. The compressed air is fed in substantially thesame manner as in the other form, except in this case all the air is fedto the nozzle 23 and is controlled by a valve 24. From the descriptionof the operation of Figs. 1 and 2 it will be understood that in the formshown in Figs. 3 and 4 the material, whether oil or grease or butlingmaterial contained in solution, is fed by gravity from the receptacle20, controlled by the valve 22, and as it passes out of the nozzle 21the compressed air from the tank 25, controlled by the valve 24:, forcesthe material onto the bufling-tool in the same manner as in the firstform.

From the above it will be seen that I have invented an apparatus forspraying or forcing liquid onto a buffing-tool, the material beingforced or ejected from the receptacle containing the same under pressurecontrolled by the operator, so that the flow may be easily and instantlykept within the requirements of the work being done.

As I have hereinbefore stated, the old method of using bufling-wheelsnecessarily limited the life of the wheels, for the reason that inactual practice it is found necessary 1 to keep the surface of the wheelin a soft and fluffy condition by the use of a suitable tool,

I and this of course causes wear and tear on the wheel, and it is soonworn away. My method of spraying, however, keeps the surface of thewheel in a soft and fiuify condition and limits the necessity ofdressing the wheel to a minimum. Moreover, when the operator dresses hiswheel under the old method quantities of dust and lint from the wheelare thrown off, which the operator cannot avoid inhaling to thesacrifice of his health. Another advantage of my apparatus is that itprevents the danger of overheating the surface of the buffing-wheel andremoves the danger of burning the Work that is being polished, whichmight otherwise destroy the cause the bufling wheel to ignite. All ofthese objections are overcome by the use of my apparatus.
